SLC Hubs/ race worthy

OT: Hi Mesa. That red doodad leaning against your battery. Could you tell me what it is and where to get one? There is one attached to a car I bought and I need the other half. Thanks,
That is one half of a quick disconnect plug, they are typically available at most race parts suppliers (Pegasus for one, probably Summit as well)
BTW: That is not the battery for the car, it uses a very strong Indura Power. Unfortunately I was in need of a stronger small battery over the Braille. Moved the Braille to the track car.
That’s great - really love to see the continued development from the factory!

Are those the race balljoints?

Fran - how about a conversion kit for us guys who have the older uprights? Could you make up a set of spacers for the rear? I jumped and picked up a set of the Dulaney adapters for the front but will eventually need some spacers for the rear.

Cam that looks like the whole upgrade right there. All you need is the bearings and the stub shafts it seams to me. John are you saying that the current production SLC (non race version) gets theses pieces. If so then this thread is pretty much complete. Just order this version from RCR and retrofit. Then you have pretty much exactly what I ended up with on my car. I wonder how much it costs.
I don't know if these will be the new standard or if they are just an option.

I also got a set of stub shafts from him so all you really need is the bearings.
Cool, John.
It's great to see these become available, very nice. Where do the spacers in the last picture go?
Mesa, yes, I'm very glad since I have been following this thread and was about to embark on the upgrade.

Not sure where those spacers go yet. I've ordered the hubs and will post progress pictures when the hubs arrive.

Spacers look like they get placed on the outside of each front upright. Since the front upright can be used for either side a removable spacer is need. If you look at the picture (post #267) you can see they are machined the same on each side of an upright.

The rear uprights also look to have removable spacers. The picture in post #263 shows them in place.

Instead of stocking four different uprights they only need two now.

I exchanged brief texts with Fran today. There are new front and rear uprights. The center section of the upright and spacer will be available as an upgrade. The new rears will accommodate C5 and C6 bearings. The rear requires a new stub axle as the bearing has a thicker shaft with higher spline count. Fran hasn’t finalized pricing yet, but the numbers he shared with me seem inline with other approaches given that it’s a complete solution. I suggested that he also drill and tap holes for the parking brake bracket. So, if you’re thinking about doing your own upgrade I’d wait... I already placed my order.

The ball joint is the track day version which he doesn’t think I need... I think I passed the installing what I don’t need line a long time ago

Great thread everyone. I have emailed Jim Dulaney and he is open to making another run of his wheel hub bearing adapters.

Looking for 5 more individuals who would want a pair. I prefer these vs. the others due to the fact they can use the C7 bearings which are significantly less expensive than the X-tracker hubs.

They are $475 for the pair shipped.
